Chris Johnson Presents: Visual Analysis of Big Data


Christopher R. Johnson Director, Scientific Computing & Imaging Institute (SCI)

In this video from PASC16 conference, Chris Johnson of the University of Utah presents: Big data visual analysis.

“We live in a time when the creation of new data is increasing exponentially, so every other day we create as much new data as we did from the beginning of mankind up to the year 2003. One of the greatest scientific challenges of the 21st century is to understand and effectively use the large amount of information produced. Visual data analysis will be one of our most important tools for understanding such large and often complex data. In this talk, I will present cutting-edge visualization techniques applied to important big data problems in science, engineering, and medicine.

One of the highlights of the presentation is the Gigapixels David project:

“The first gigapixel multi-view rendering of David from the Digital Michelangelo Project can now be downloaded and viewed on your iPhone. The ViSUS Gigapixel David app lets you explore the digital laser scan of the statue of David in great detail. With a simple pinch or spread of the fingers, users can zoom in and out to explore details such as the piercing marks and scratches left by artist Michelangelo.

visus-david_newsThe David model consists of 933 million triangles from a laser scan of the original statue created by Professor Marc Levoy and members of the Digital Michelangelo Project at Stanford University. The original data consists of 8 million polygons, each approximately 2.0mm in size, less than the thickness of 2 dimes.

Chris Johnson is the founding director of Scientific Computing and Imaging (SCI) Institute of the University of Utah where he is professor emeritus of computer science and holds professorships in the departments of physics and bioengineering. His research interests lie in the fields of scientific computing and scientific visualization. Professor Johnson founded the SCI Research Group in 1992, which has since grown into the SCI Institute, employing more than 200 professors, staff and students. Professor Johnson sits on several editorial boards of international journals, as well as advisory boards of national research centers. Professor Johnson has received a number of awards, including the NSF Presidential Faculty Fellow (PFF) from President Clinton in 1995 and the Governor’s Medal for Science and Technology from Governor Michael Leavitt in 1999. He is a fellow of the American Institute for Medical and Biological Engineering, Fellow of the American Association for the Advancement of Science, and in 2009 he was elected Fellow of the Society for Industrial and Applied Mathematics (SIAM) and received the Utah Cyber ​​Pioneer Award. In 2010, he received the Rosenblatt Award from the University of Utah and the IEEE Visualization Career Award. In 2012 he received the IEEE IPSPS Charles Babbage Prize and in 2013 the IEEE Sidney Fernbach Prize. In 2014, Professor Johnson was elected a Fellow of the IEEE.
